It's the only non-turbo engine in IMSA's new WeatherTech SportsCar Championship hybrid GTP class and it makes incredible sounds while generating a ton of power.
Take a look at the power behind the Cadillac V-LMDh which makes its racing debut at the Rolex 24 At Daytona.

This engine sounds awesome !

@TheQuietStorm6000 Год назад

Wow. I'm a big GM fan and totally missed this one. I watch Le Mans yearly and cheer the Corvette on. I did not realize Cadillac had planned to re-enter Le Mans. This engine was impressive. Cadillac finished race at 3rd and 4th. I know its not first but it seems impressive for this engine. I'm happy Corvette one 1st in the GT Class. Go Chevrolet and Cadillac!!!!

@V8Supercar1 10 месяцев назад

You missed a treat. Great race. This car did really well battling the heavily favored Ferrari and Toyota teams all night. Cadillac even lead the race for a short while.

Great series!!! The Caddy sounds awesome.

@paulhutton1507 Год назад

When they first announced that they’re using a 5.5 V8 I figured it was based on the C8R engine.

@TheNecromancer6666 Год назад

That or the old DPi engine with a higher rev range. Building a completely New one is insanely cool, but absolutely nonsensical.

@byates59 Год назад

@@TheNecromancer6666 The old DPi engine was a single cam in block, overhead value, push rod engine with a cross plane crank shaft. This new engine is double overhead cams with a cross plane crank shaft!

@TheNecromancer6666 Год назад

@@byates59 Apparently so yes. The old one was basicly a race modified LT1. This New one is a 100% Prototype engine. Insanely cool but still kinda insane.

@jazzbassrocker Год назад

I still have a sneaking suspicion that it's the C8.R block and heads with a crossplane crank and corresponding firing order to give it that unique sound.

@user-hd4wf5gq8r Год назад

So if we got a cross plane in the new Z06 this is what it might sound like, interesting…

pretty sure the DPi engine would have revved to like 11k if it was allowed to by imsa. the technology was there from the Cup program

You are still getting the Power numbers wrong. Its a 500kw wheel power performance Target. But the engine Power is 15% higher, around 575kw. So its mot a 670hp engine. Its a 770hp engine.

@mememanfresh Год назад

bruh wdym there not allowed over 670

@TheNecromancer6666 Год назад

@@mememanfresh Did you read my comment? The Power is measured at the wheels. So including Transmission losses. Which are around 15%. That means the 500kw at the wheels are 575kw at the crankshaft. Also they don't have a hard Limit they have a Performance Window which is between 500 and 520kw at the wheels depending on the BoP

@basilb4733 Год назад

Is it a crossplane V8?

@silverbulletgarage309 Год назад

Nope you can tell by how it sounds more like a classic American V8

@FarmYardGaming Год назад

So yes... it is a crossplane V8. Not a flatplane.

@StreetComp Год назад

Isn’t the Corvette C8 Z06 using a 5.5L V8 that revs to 8600rpm? Though GM should be getting plenty of xp with DOHC NA engines in the C8.R

@ByGraceThroughFaith777 Месяц назад

This is what GM could put on road cars if it wasn't for all the epa regulations and electronics that modern cars require. Pure compression and cam design optimized for performance, nothing more. Put that dame engine in a street vehicle and it's game over.

What's with your head all of you Americans? 2.4 liter displacement is a tiny for you guys? Having too much displacement like a 5.5 liter LS engine still call it small block for that displacement WTH. XD

@griffinfaulkner3514 Год назад

You have to remember that an LS engine is absolutely microscopic relative to its displacement because of its pushrod design. An LS7, with its massive 7 liters of displacement, is both lighter and has smaller exterior dimensions than BMW's 4 liter S65 V8.
